The safety check is now incorporated into the standard Bell 206 maintenance manual as part of the routine 300-hourly inspection. This effectively folds a special one-off safety directive into normal scheduled maintenance, simplifying compliance for aircraft operators."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-206-91-amdt-1-longeron-p-n-206-031-314-inspection-and-repair-cancelled","history":"/api/acts/ad-bell-206-91-amdt-1-longeron-p-n-206-031-314-inspection-and-repair-cancelled/history","analysis":"/api/acts/ad-bell-206-91-amdt-1-longeron-p-n-206-031-314-inspection-and-repair-cancelled/analysis","conflicts":"/api/acts/ad-bell-206-91-amdt-1-longeron-p-n-206-031-314-inspection-and-repair-cancelled/conflicts","importantCases":"/api/acts/ad-bell-206-91-amdt-1-longeron-p-n-206-031-314-inspection-and-repair-cancelled/important-cases","documents":"/api/acts/ad-bell-206-91-amdt-1-longeron-p-n-206-031-314-inspection-and-repair-cancelled/documents"}}
